PRECAUTION
(1) Voltage compensate capacitors are expected to be located as close as possible to the Hybrid IC.
(2) Minimize the area of closed circuit of gate circuit so as not to be affected by induction noise.
(3) D1 requires approximately the same voltage of power modules.
(4) When recovery current flow in D1 , pin 30 is applied high voltage .
I
In that case , counterplan for protection which insert a zener diode between pin
21,22 and 30 are necessary like above diagram.
